General tips on milling/turning copper
Edit.Ps: I dont see any nee for carbide. While it is mentioned on occasion that copper causes abrasive tool wear i guess thats only because its way too soft to cause cracking or heat related damage ant normal parameters. After all pretty much every copper alloy can be used as a plain bearing to some degree.
